      abstract     = {The Belle II experiment at the super KEK B-factory
                      (SuperKEKB) in Tsukuba, Japan, has been collecting $e^+e^-$
                      collision data since March 2019. Operating at a
                      record-breaking luminosity of up to $4.7\times10^{34} \
                      cm^{-2}s^{-1}$, data corresponding to $424 \ fb^{-1}$ has
                      since been recorded. The Belle II VerteX Detector (VXD) is
                      central to the Belle II detector and its physics program and
                      plays a crucial role in reconstructing precise primary and
                      decay vertices. It consists of the outer 4-layer Silicon
                      Vertex Detector (SVD) using double sided silicon strips and
                      the inner two-layer PiXel Detector (PXD) based on the
                      Depleted P-channel Field Effect Transistor (DePFET)
                      technology. The PXD DePFET structure combines signal
                      generation and amplification within pixels with a minimum
                      pitch of $(50 \times 55) \ μm^2$. A high gain and a high
                      signal-to-noise ratio allow thinning the pixels to $75 \
                      μm$ while retaining a high pixel hit efficiency of about
                      $99 \\%$. As a consequence, also the material budget of the
                      full detector is kept low at $\approx 0.21\\% \frac{X}{X_0}$
                      per layer in the acceptance region. This also includes
                      contributions from the control, Analog-to-DigitalConverter
                      (ADC), and data processing Application Specific Integrated
                      Circuits (ASICs) as well as from cooling and support
                      structures. This article will present the experience gained
                      from four years of operating PXD; the first full scale
                      detector employing the DePFET technology in High Energy
                      Physics. Overall, the PXD has met the expectations.
                      Operating in the intense SuperKEKB environment poses many
                      challenges that will also be discussed. The current PXD
                      system remains incomplete with only 20 out of 40 modules
                      having been installed. A full replacement has been
                      constructed and is currently in its final testing stage
                      before it will be installed into Belle II during the ongoing
                      long shutdown that will last throughout 2023.},
